Over the past two decades, wireless technologies operating at traditional frequency bands (6GHz) evolved into data intensive communication systems by enjoying innovations such as cognitive radio, multiple antenna systems, heterogeneous networks, and machine-to-machine communications. These innovations are currently not satisfactory to address the significantly enhanced data rate needs for future generations (5G and beyond) of wireless communication systems. Consequently, wider frequency bandwidths available at mm-Wave bands (above 10GHz) have recently attracted a strong interest from the wireless community to be able to serve the future data rate demands. Therefore, in this project, the aim is to enhance the capacity and the data rate of wireless communication systems based on the wireless channel control phenomenon by investigating the use of spatial (i.e. position) adaptation of smart antenna arrays. At mm-Wave bands, position adaptations on the order of a few centimeters can practically be realized within compact devices and yet provide new wireless channel opportunities and interference mitigation. The preliminary studies demonstrate that wireless channel opportunities achieved through such spatial adaptations can improve the wireless system capacity beyond a factor of 2.5 to 5. Hence, the results of this project are expected to be transformative in adaptive wireless communications area and the resulting knowledge base is expected to have effects on commercial, emergency, and military communication domains. Immediate tangible outcome of this project will be a system level test bed that will provide results, outcomes, and design guidelines to prospective designers within academia and industry. The proposed activity will also lead to improve the curriculums through developing lab experiments and test beds. Efforts will be made to incite the participation of the minority students via seminars, technology fairs, and specialized events. Broad dissemination is ensured via conference and journal publications, workshops, and tutorials. Specialized outreach sessions will be organized at local high schools and community colleges to expose and attract students, particularly minorities to STEM disciplines.This proposal introduces a novel wireless system adaptation strategy based on repositioning of mm-Wave antenna arrays during the system operation to control the wireless channel gain. The recent developments in the areas of microfluidic based reconfigurable RF devices and multi-dimensional (i.e. frequency, time, and spatial domains) dynamic spectrum access techniques are jointly investigated, for the first time, to significantly enhance wireless communication system performance. Beam and position adaptable antennas at the transmitter and receiver are used to control the multipath channel characteristics so that a favorable effective channel response for the communication link can be obtained. Unlike the on-going research efforts that focus on mm-Wave wireless systems harnessing beam-steering capability, the proposed system envisions a paradigm shift in the physical layer by controlling the wireless channel using a combination of the beam-steering and position adapting functionalities. Position adaptation is planned to be carried out in a compact, efficient, and high precision device by introducing microfluidically reconfigurable feed networks. The proposed unusual combination of beam-steering and position reconfiguration generates a need for this proposed effort to investigate and revise the long-time established channel estimation, tracking, prediction, and compensation techniques. The proposed main research thrusts are (1) Controlling mm-Wave Wireless Channel; (2) System Design in Heterogeneous Networks; (3) Spatially Adaptive Smart mm-Wave Antenna Arrays; (4) Verification of Theory Predicted Channel Capacity Enhancement with mm-Wave Wireless Communication Scenarios.

在过去的二十年中，在传统频段（6 GHz）上运行的无线技术通过享受诸如认知无线电、多天线系统、异构网络和机器对机器通信等创新而演变成数据密集型通信系统。这些创新目前不能满足未来几代（5G及以后）无线通信系统的显著增强的数据速率需求。因此，在毫米波频带（10 GHz以上）处可用的更宽的频率带宽最近已经吸引了来自无线社区的强烈兴趣，以能够服务于未来的数据速率需求。因此，在这个项目中，目的是通过研究智能天线阵列的空间（即位置）自适应的使用，以提高无线通信系统的容量和数据速率的无线信道控制现象的基础上。在毫米波波段，几厘米量级的位置自适应实际上可以在紧凑的设备内实现，并且还提供新的无线信道机会和干扰缓解。初步研究表明，通过这种空间适应实现的无线信道机会可以提高无线系统容量超过2.5至5倍。因此，该项目的结果预计将是变革性的自适应无线通信领域和由此产生的知识库预计将对商业，应急和军事通信领域的影响。该项目的直接有形成果将是一个系统级测试平台，将为学术界和工业界的潜在设计师提供结果，成果和设计指南。拟议的活动还将通过开发实验室实验和试验台来改进实验室。将努力通过研讨会、技术展览会和专门活动鼓励少数民族学生参与。通过会议和期刊出版物、讲习班和教程确保广泛传播。将在当地高中和社区学院组织专门的外展会议，以接触和吸引学生，特别是少数民族的STEM学科。该提案介绍了一种新的无线系统适应战略的基础上重新定位的毫米波天线阵列在系统操作，以控制无线信道增益。基于微流体的可重构RF器件和多维（即频率，时间和空间域）动态频谱接入技术领域的最新发展首次联合研究，以显着提高无线通信系统的性能。发射机和接收机处的波束和位置自适应天线用于控制多径信道特性，使得可以获得通信链路的有利的有效信道响应。 与专注于利用波束转向能力的毫米波无线系统的正在进行的研究工作不同，所提出的系统设想通过使用波束转向和位置自适应功能的组合来控制无线信道，从而在物理层中实现范式转变。计划通过引入微流体可重新配置的馈送网络，在紧凑、高效和高精度的设备中进行位置适应。所提出的波束转向和位置重新配置的不寻常组合产生了对所提出的努力的需求，以调查和修改长期建立的信道估计、跟踪、预测和补偿技术。主要研究方向为：（1）毫米波无线信道控制;（2）异构网络中的系统设计;（3）空间自适应智能毫米波天线阵列;（4）毫米波无线通信场景下信道容量增强理论的验证。
